Table 11 Verify level 2 values field descriptions
DescriptionField
Maximum number of frames that can be transmitted without an acknowledgment.
The range is 1 through 7 for Modulo-8 and 1 through 127 for Modulo-128. The
default is 7. Use the value given on your subscription form.
k - Level 2 Window Size
Maximum number of milliseconds to wait for an acknowledgment before retransmitting
a frame. The range is 100 to 12000. The default is 3000. Use the value given on
your subscription form.
T1 - Retransmission Timer
Maximum number of milliseconds that a line can be idle before it is declared
disconnected. This value should be greater than or equal to the Retransmission Timer
T3 - Idle Timer
(T1) times the Retransmission Count (N2). The range is 1000 to 240000. The default
is 60000. Use the value given on your subscription form.
Maximum number of octets that can be transmitted in a single frame. The range is
149 (minimum) through 4103. The default is 149.
N1 - Frame Size
Maximum number of times a given frame can be transmitted before an error condition
is identified. The range is 0 through 255. The default is 20.
N2 - Retransmission Count
NOTE: Because the timer values count the amount of time between unacknowledged frames,
you may need to increase the values of T1 (Retransmission Timer) and T3 (Idle Timer) if you
use Modulo-128 with a window size greater than seven.
3. Click OK to return to the Configure X.25 Card dialog when you have finished verifying level
2 values.
4. Click OK to complete X.25 software configuration and save your changes. Your X.25 interface
(port) should appear in the object list with status Enabled (no problem found and link
connected correctly). If not, carefully repeat the steps in this chapter until the configuration is
enabled.
If your port is not connected to a running network, it will display as configured.
You have completed the interface configuration.
5. Select Exit from the File menu if you have no need to configure access to other systems or to
PAD services. Then exit SMH.
If you need to configure access to other systems or configure PAD services, stay in SMH and
continue with the instructions in “Configuring remote system access” (page 23) (to configure
access to other systems) and in “Configuring PAD services” (page 55) (to configure PAD
services).
NOTE: Your system will not reboot when you exit. Your configuration is effective immediately
without the need to create a new kernel.
If you want to control Services (Internet/Berkeley Services or Network Services (NS)), refer to the
documentation set for those products.
Configuring remote system access
Follow the steps below to configure access to other hosts and systems that use TCP/IP protocol.
(The procedures in this section are optional. Your X.25 link software does not require that you
configure access to other systems).
